Conference Paper

STUDY OBJECTIVE: To establish construct validity of the simulated vaginal hysterectomy trainer (SimVaHT). DESIGN: A cross-sectional validation study (Canadian Task Force classification II-2). SETTING: A single academic medical center in the United States. SUBJECTS: Fourteen residents in obstetrics and gynecology (4 postgraduate year [PGY] 1, 4 PGY-2, 3 PGY-3 and 3 PGY-4). PGY-1 and PGY-2 residents were grouped to form the "junior level" cohort, whereas PGY-3 and PGY-4 residents comprised the "senior level" cohort. INTERVENTIONS: Each participant underwent surgical skill simulation by performing a simulated vaginal hysterectomy on a practical, inexpensive vaginal hysterectomy trainer. MEASUREMENTS AND MAIN RESULTS: The primary outcome was resident surgical skill as assessed by the Objective Structured Assessment of Technical Skills Global Rating Scale (GRS). All obstetrics and gynecology residents were videotaped performing a simulated vaginal hysterectomy on the SimVaHT. The tapes were reviewed independently by 2 blinded urogynecology experts, each of whom provided a GRS score. The primary outcome was overall GRS scores. The secondary outcome was time to complete the exercise. GRS scores were compared between junior- and senior-level residents. Senior-level residents scored significantly higher on the GRS overall compared with junior-level residents (p = .008). CONCLUSION: Construct validity was demonstrated for the SimVaHT. The SimVaHT is a practical and inexpensive tool that may improve resident vaginal surgical skills before their first case in the operating room.
